PIC 16F876 LCD RF Power Meter

       PM1:   (Old Version, Only PCB available)

       PM2:   (New, Incl Sensor circuit on PCB) Kits & PCBs

coming soon

This 2x20 LCD HF/VHF SWR Meter measures & Display SWR and Forward power and has a bar graph too. Uses PIC16F88 with inbuilt 8MHZ Osc. and has 3 front panel buttons for menu control.

Uses standard PL/SO239 sockets. 

Radio amateurs showed great interest in my PM1 RF Power meter detailed below. (PCBs still available)

However, requirement of separate sensor board and an encoder was not convenient to many home brewers. 

This, Re-Designed, RF Power meter uses push buttons for menu operation, much smaller in size, has dual RF inputs (Dual Sensor circuit already built-in) & uses DIP8 AD8307 which, you may buy directly from Analog Devices or Digikey and install.

PCBs and Complete Kit Available

A PIC 16F876A Power Meter is a very useful instrument if you are working with RF Circuit Designing. This LCD meter has 2x20 LCD, a Rotary encoder & two menu push buttons. 

Only PCB for this project are available

0-500MHZ RF Sensor

Originally used with PM1: RF Power Meter

500MHZ RF Sensor uses an AD8307 from Analog Device. This Kit has two possible input channels which may be used with a SWR probe to measure SWR. Presently only one SMD AD8307 is supplied with kit. The second channel may be activated by inserting DIP AD8307 which is available from DIGIKEY.

Only PCBs are available
